I need to read up more on the Glickman Chess Rating system to see how it differs from that of the Game Courier Rating system, seeing as how they seem to share the same acronym. I was suggesting, on the other hand, a way of measuring computer programs pitted against each other, and against humans that are allowed to compete with them. You've probably heard of http://www.pogo.com where you can play cardgames such as Hearts and Spades (but no Skat, the last time I looked). You even get to play with robot players if you want. There are lots of sites like that in Internet. It's my understanding that the Game Courier here at www.chessvariants.org could handle cardgames like that, though one might be a tad less graphical than another. As for ZOG being some kind of a reason to forbid the 'Game Plies Rating' system I suggested, that only applies to people unwilling to buy an upgraded ZOG with the feature I suggested. Since I don't have a copy of Zillions of Games (and I'm unusually reluctant to go out and buy something that I don't even have a hardware platform to run it on), it escapes me why, exactly, the program can't be upgraded to play out all the plies that it has been directed to search through, short of observing that the person who originally programmed it, must not have felt like designing that feature. It was probably a case of him shrugging, and saying, 'Why bother?' If someone gets around to upgrading ZOG so it *could* search through entire Plies' worth of information (with or without regard to time controls, or the peculiar predicaments inherent in data storage), I'm sure it could do the job just as well as the next one could.
